	instead of using explicit *_CHAR codes.
202 203
	(bidi_resolve_explicit, bidi_resolve_weak):

	handle_display_spec instead of single_display_spec_intangible_p.
221 222

	* lisp.h: Change signatures accordingly.
	* alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
	All callers changed.  (Bug#8762)

	* gnutls.c: Use Emacs's memory allocators.
	Without this change, the gnutls library would invoke malloc etc.
	directly, which causes problems on non-SYNC_INPUT hosts, and which
	runs afoul of improving memory_full behavior.  (Bug#8761)
	(fn_gnutls_global_set_mem_functions): New macro or function pointer.
	(emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
	xfree instead of the default malloc, realloc, free.
	(Fgnutls_boot): No need to check for memory allocation failure,
	since xmalloc does that for us.

	Use it instead of discarding useful hash info with large hash values.
	(sxhash_float): New function.

	(MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
	(pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
	(Fformat): Avoid the prepass trying to compute sizes; it was only
	approximate and thus did not catch overflow reliably.  Instead, walk
	through the format just once, formatting and computing sizes as we go,
	checking for integer overflow at every step, and allocating a larger
	buffer as needed.  Keep track separately whether the format is
	multibyte.  Keep only the most-recently calculated precision, rather
	than them all.  Record whether each argument has been converted to
	string.  Use EMACS_INT, not int, for byte and char and arg counts.

	and %.0c.  Fix bug with strchr succeeding on '\0' when looking for

	(arith_driver): When there's an integer overflow in an expression
	involving floating point, convert the integers to floating point
	so that the resulting value does not suffer from catastrophic
	integer truncation.  For example, on a 64-bit host (* 4
	most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.

2011-05-07  Ben Key  <bkey76@gmail.com>

	* makefile.w32-in: The bootstrap-temacs rule now makes use of
	one of two shell specific rules, either bootstrap-temacs-CMD or
	bootstrap-temacs-SH.  The bootstrap-temacs-SH rule is identical
	to the previous implementation of the bootstrap-temacs rule.
	The bootstrap-temacs-CMD rule is similar to the previous
	implementation of the bootstrap-temacs rule except that it
	makes use of the ESC_CFLAGS variable instead of the CFLAGS
	variable.

	These changes, along with some changes to nt/configure.bat,
	nt/gmake.defs, and nt/nmake.defs, are required to extend my
	earlier fix to add support for --cflags and --ldflags options
	that include quotes so that it works whether make uses cmd or
	sh as the shell.

928

929 930 931

	(EMACS_UINTPTR): Likewise, with uintptr_t.

932 933 934 935
	* lisp.h: Prefer 64-bit EMACS_INT if available.
	(EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
	on 32-bit hosts that have 64-bit int, so that they can access
	large files.
936 937
	However, temporarily disable this change unless the temporary
	symbol WIDE_EMACS_INT is defined.
938

939 940
	* lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.

941 942 943 944 945 946 947 948 949 950 951 952 953 954 955 956 957 958 959 960 961 962 963 964 965 966 967 968 969 970
	Prefer intptr_t/uintptr_t for integers the same widths as pointers.
	This removes an assumption that EMACS_INT and long are the same
	width as pointers.  The assumption is true for Emacs porting targets
	now, but we want to make other targets possible.
	* lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
	(EMACS_INTPTR, EMACS_UINTPTR): New macros.
	In the rest of the code, change types of integers that hold casted
	pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
	replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
	(XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
	(XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
	No need to cast type when ORing.
	(XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
	* alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
	* doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
	assume EMACS_INT is the same width as char *.
	* gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
	(xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
	Remove no-longer-needed casts.
	(xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
	(xg_tool_bar_help_callback, xg_make_tool_item):
	Use EMACS_INTPTR to hold an integer
	that will be cast to void *; this can avoid a GCC warning
	if EMACS_INT is not the same width as void *.
	* menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
	* xdisp.c (display_echo_area_1, resize_mini_window_1):
	(current_message_1, set_message_1):
	Use a local to convert to proper width without a cast.
	* xmenu.c (dialog_selection_callback): Likewise.

971 972 973 974 975 976
	* sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
	Also, don't assume VALBITS / RAND_BITS is less than 5,
	and don't rely on undefined behavior when shifting a 1 left into
	the sign bit.
	* lisp.h (get_random): Change signature to match.

977 978 979 980 981 982 983 984
	* lread.c (hash_string): Use size_t, not int, for hash computation.
	Normally we prefer signed values; but hashing is special, because
	it's better to use unsigned division on hash table sizes so that
	the remainder is nonnegative.  Also, size_t is the natural width
	for hashing into memory.  The previous code used 'int', which doesn't
	retain enough info to hash well into very large tables.
	(oblookup, oblookup_last_bucket_number, Funintern): Likewise.

985 986 987 988 989
	* dbusbind.c: Don't possibly lose pointer info when converting.
	(xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
	Use XPNTR rather than XHASH, so that the high-order bits of
	the pointer aren't lost when converting through void *.

990 991
	* eval.c (Fautoload): Don't double-shift a pointer.

992 993
	* fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.

	* lisp.h: Fix a problem with aliasing and vector headers.  (Bug#8546)
1230 1231
	GCC 4.6.0 optimizes based on type-based alias analysis.
	For example, if b is of type struct buffer * and v of type struct
1232 1233 1234 1235 1236
	Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
	!= &v->size, and therefore "v->size = 1; b->size = 2; return
	v->size;" must therefore return 1.  This assumption is incorrect
	for Emacs, since it type-puns struct Lisp_Vector * with many other
	types.  To fix this problem, this patch adds a new type struct

	vectorlike_header that documents the constraints on layout of vectors

	Make the Lisp reader and string-to-float more consistent (Bug#8525)
1282 1283 1284 1285 1286 1287 1288 1289 1290 1291
	* data.c (atof): Remove decl; no longer used or needed.
	(digit_to_number): Move to lread.c.
	(Fstring_to_number): Use new string_to_number function, to be
	consistent with how the Lisp reader treats infinities and NaNs.
	Do not assume that floating-point numbers represent EMACS_INT
	without losing information; this is not true on most 64-bit hosts.
	Avoid double-rounding errors, by insisting on integers when
	parsing non-base-10 numbers, as the documentation specifies.
	* lisp.h (string_to_number): New decl, replacing ...
	(isfloat_string): Remove.
1292
	* lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
1293
	(read1): Do not accept +. and -. as integers; this
1294 1295 1296 1297 1298 1299 1300
	appears to have been a coding error.  Similarly, do not accept
	strings like +-1e0 as floating point numbers.  Do not report
	overflow for integer overflows unless the base is not 10 which
	means we have no simple and reliable way to continue.
	Break out the floating-point parsing into a new
	function string_to_number, so that Fstring_to_number parses
	floating point numbers consistently with the Lisp reader.
1301
	(digit_to_number): Move here from data.c.  Make it static inline.
1302 1303 1304 1305 1306
	(E_CHAR, EXP_INT): Remove, replacing with ...
	(E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
	(string_to_number): New function, replacing isfloat_string.
	This function checks for valid syntax and produces the resulting
	Lisp float number too.  Rework it so that string-to-number
1307
	no longer mishandles examples like "1.0e+".  Use strtoumax,
1308 1309
	so that overflow for non-base-10 numbers is reported only when
	there's no portable and simple way to convert to floating point.

	* frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right

	which are not wanted; and it overflows with large numbers.
	Instead, simply match F[0-9]+, which is what is wanted anyway.

	(allocate_vectorlike, make_pure_vector): Use the new macros,
	plus offsetof, to remove unportable assumptions about struct layout.
	These assumptions hold on all porting targets that I know of, but
	they are not guaranteed, they're easy to remove, and removing them
	makes further changes easier.

1400 1401

	don't formally overflow signed char, to avoid warnings.
1404 1405
	(allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
	can cause Emacs to crash when string overrun checking is enabled.
1406 1407 1408
	(allocate_buffer): Don't assume sizeof (struct buffer) is a
	multiple of sizeof (EMACS_INT); it need not be, if
	alignof(EMACS_INT) < sizeof (EMACS_INT).
1409
	(check_sblock, check_string_bytes, check_string_free_list): Protoize.
